Power supply system and energy storage system

Abstract:

A power supply system to provide auxiliary power output comprising a first energy storage device, a first inverter coupled to the first energy storage device, a first transformer, a first diode and a capacitor. The first inverter includes a first switch and second switch in series. The first transformer transforms high voltage from the first energy storage device to the low voltage output from auxiliary power output terminal, and includes the primary winding and auxiliary winding. The primary winding is connected to the first energy storage device and the junction of the first and second switch, and the homonymous terminal of the secondary winding is connected to the auxiliary power output through the first diode, with the synonymous terminal connected to the earth. One end of the first capacitor is connected to the first diode cathode and the other end is connected to the earth.
